Application led March 13, 1916. Serial No. 83,953.

To all whom t may concern Be it known that we, WILLIAM H. GAR- LooK and WILLIAM J. STUBBE, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Bread-Slicers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bread cutters, and morey especially to those wherein the knives reciprocate; and the object of the same is to produce a machine for cutting loaves of food such as bread into slices.

The invention consists in the general and detail structure of parts, and more particularly in the means for removing the slices.

Details are set forth in the following specification and are shown in the drawings wherein:

Figure 1 is a side elevation of the machine complete, Fig. 2 a vertical longitudinal section, Fig. 3 a plan view, Fig. 4 a cross section on the line 4--4 of Fig. 3, and Fig. 5 a front elevation with the rest omitted. Fig. 6 is a. detail to be referred to hereinafter. Fig. 7 is a longitudinal section showing the carriage at the rear and the front edge of the leaf swung downward, while Fig. 8 is a similar section showing the carri-age at the front and the leaf raised. y Fig. 9 is a plan view of the upper rail of one'frame on an enlarged scale.

Referring by reference numerals to the drawing, legs 1 support a table 2 having in its top a considerable opening 3 with guides 4 along the side edges thereof, upon which travels a carriage designated broadly by the numeral 5, the carriage being as wide as the opening but not as deep and therefore capable of reciprocation forward and backward upon the guides 4. The reciprocating means shown herein include a bracket 6 pivotally supporting a bell-crank lever 7, a link 8 connecting one arm of this lever with the carriageI at the point 9, and a link 10 connecting the other arm of the lever wth a treadle 11 having a foot piece or pedal 12 at its-front end and a weight 13 at its rear end. Whenlthe pedal is depressed the link 10 causes the lever 7 toy rock on its' pivot, and this motion through the link 8 causes the carriage 5 to move from the full line position in Fig. 1 back to the position shown in dotted lines; but when pressure is removed from pedal 12 the weight 13 restores the parts to their initial position.

The cutting mechanism includes a pair of upright guides 20 in which move two frames 21 and 22, each carrying a series of saw blades or knives 23, and the knives being alternated with each other as best seen in Fig. 5. Both the top and bottom rails of each frame are composed of two spaced bars, and the knives have threaded set bolts 24 at their ends extending between the bars and receiving nuts 25 whereby any knife can be tightened or a broken or dull knife may be replaced. The set bolts 24 and nuts 25 also may be used for setting the knives farther apart or nearer together, if desired, for varying the thickness'of the slices. The lower rail of each frame carries a casting having an eye 26 to which is pivoted a link 27, and the lower ends of the two links engage cranks 28 in a crank shaft 29 which is journaled in suitable bearings in the framework 1 of the table. `As herein shown the shaft 29 carries a pulley 30 connected by a belt 31 with' another pulley 32 fast on a power shaft 33, and the latter may be driven bymachine power or by hand power as by means of the crank wheel 34 best seen in Fig. 5. When the power shaft is rotated it rotates the crank shaft 29, and the oppositelydisposed cranks 28 thereon cause the simultaneous reciprocation of the two frames 21 and 22 in opposite directions, so that their lgangs of knives move upward and downward through the loaf when the latter is fed to'them.

The carriage 5 referred to above comprises front and rear cross bars 35 and 36 \which are rigidly connected by a slotted plate 37 extending between and passing over them and secured upon them,'as by screws 38, and the slots 39 in thisplate are made as wide as possible so that the knives 23 may pass freely through them. Between the cross bars and beneath said plate is disposed a leaf 40, which may well be a slotted board of less length than said bars so that its ends do not rest on guides 4, and of such width that it is free between the strips. Its rear edge is hinged as at 41 to the rear bar 36 and near its front edge it carries laterally projecting pins 42. Each pin works freely in a slotted cam or track 43 whose shape is best seen in Fig. 6. The ends vof the bars 35 and 36 travel along said guide, whereas the pin 42 travels in the track 43 and stands normally at the front end of the same as best seen in Fig. 2. The slots 49 in leaf 40 are for the passage of the knives 23 as also best seen in Fig. 2. Rising from the slats between said slots 49, and at certain points throughout the length of this leaf, are pins or spurs 46 which normally project through elongated openings 47 that are formed in the slats of the plate 37 between its slots 39, and the purpose of elongating these openings is to permit the spurs to be swung upward and downward through them during the movements of the leaf as described below. If desired, a rest 50 may be secured upon the table 2 and will extend completely across the carriage, so that the latter can move freely beneath it. This rest is shown in Figs. 1, 2 and 3, but omitted in Fig. 5.

An important feature of our invention is the mechanismfor removing the slices, or for holding them so that they will not be d rawn back against the saws when the carriage returns for a second loaf. Near the rear edge of the table 2 and in rear of the opening 3 are two pairs `of posts 5l, each pair supporting a longitudinal rod 52, and on the rod between the posts slides a block 53 to which at 54 is pivoted an upright arm 55, while a spur 56 projects rearward and downward from this arm above said pivot and will maintain the arm normally in upright position as seen in Fig. 1. The two arms are connected near their upper ends by a rod 57 which constitutes a bail, or in fact the two arms 55 could be bent toward each other and connected to produce this bail, or the arms might be integrally connected thereby so that they `would be both formed from one piece of metal.

Inv the operation of this machine, power lbeing imparted to the shaft 33 and the knives reciprocating, one workman takes his place at the front of the machine and places a loaf L on .the carriage plate against the rest 50 as seen in Fig. 2. Then when he depresses the treadle 11 the carriage moves to the rear andthe spurs 46-carry the .loaf through the knives which cut it into slices. `Meanwhile the pins 42 lmove in the tracks '43 from the position shown in Fig. 8 to that in Fig. 7

and cause the leaf 40 to swing downward at its front edge so that as the loaf has passed through the knives the spurs are drawn out of it. A second operator at the rear or at the side of the machine now throws the arms 55 downward so that the rod or bail 57 is passed in between the slices and the rear edge of the rearmost knives, and the entire ejecting mechanism is then moved to the rear by sliding the two blocks 53 on the rods 52. Meanwhile a release of pressure on the treadle 1l has permitted the weight 13 t0 restore the carriage to its initial position, and in doing so the plate 37 which has sustained the slices is drawn from under them while they are held by the rod 57, and they fall through the opening 3 in the table top 2 and into a suitable receptacle beneath. If preferred, they may have been lifted bodily oil' the plate 37 of the carriage by this operator,

yas for instance when they are slices of frosted cake which it is necessary to handle carefully. But in either case the use of the ejecting mechanism is to prevent the freshly cut slices from coming in contact or being drawn in contact with the rear edges of the rearmost knives, to the detriment of slices of cake or other soft food material. We do not wish to be limited to the precise details herein set forth. Especially with respect to the knives do we reserve the privilege of making considerable change if desired. While we prefer knives in two gangs reciprocating oppositely as described, it is quite possible that rota-ry or other cutting means might be employed.

YVhat we claim is:

In a loaf slicing machine, the combination with a table top having an opening and the cutting mechanism working therein, of guides along the side edges of said opening, castings let into said guides and each having a track including a rearwardly inclined leg, a carriage mounted on said guides'and including a slotted plate and a leaf hinged at its rear edge and provided with pins at its front edge engaging said track, spurs rising from the leaf, and means for reciprocating the carriage.
